This function and below get_num_sge() need fix.  We have supposed to pass
pointer of struct RAID_CONTEXT_G35 to get correct setting reflected in IO
frame, otherwise it just set in stack local memory and that is not a
intent here. We will fix this patch and resend. Only fixing this patch and
resend works fine with complete series (there is no hunk failure observe),
so just going to push one particular patch with below title.
